CORD GRIP FOR ELECTRIC FITTINGS AND APPLIANCES.

Application filed July 1, 1926, Serial No. 119,957, and in Great BritainJuly 14, 1925.

to or forming a part'of the lamp holder or the like, said head beingarranged for the admission of the leads or flexible conductors fromopposite sides of a central aperture and a plug adapted forinsertionbetween the leads to wedge or bind them securely to the said head,whilst maintaining them apart at the place where they are gripped.

Referring to the accompanying sheet of explanatory drawings Figure l isa sectional elevation of a head and plug as aforesaid and Figure 2 aplan of the same.

Figure 3 is a sectional elevation and Figure l a plan showing anotherform of such head and plug.

The same reference letters in the different views indicate the same orsimilar parts.

In the example shown at Figures 1 and 2, the head a of vulcanized fibreor other insulating material is screwed directly int-o the top of a lampholder of which a portion is indicated at b. The said head has atransverse slot forming lateral grooves or apertures as 0 leading intothe central aperture 0?. The outer end of said central aperture d isthreaded to receive the screw plug 6 having a tapered inner end asshown. The leads or flexible conductorsindicated by let ters f arethreaded through thelateral apertures a and thence passed by way of thecentral aperture (Z to the interior of the holder 5 where, in the usualmanner they are attached to the terminals or'like parts, not Shown. Bymeans of the screw plug e the leads are kept separate as illustrated andsecurely wedged or clamped to the head a.

In the example shown at Figures 3 and 4: the head a forms a part of thelamp holder itself, but in other respects it is similar to the examplegiven by Figures 1 and 2.

What I claim is 1. In cord grips for electric fittings and appliances,the combination comprising an insulating head piece having a centralaperture extending therethlough and a trans- 6O verse slot forminglateral grooves extending from the opposite sidesof the head piece tothe central aperture, electricity conducting cords passing through saidlateral grooves and central aperture, and a plug 66 screwed into theouter end of the said central aperture and seating upon the saidconducting cords, as set forth.

2. In cord grips for electric fittings and appliances, the combinationcomprising a 70 holder, an insulating head piece in detachableconnection with said holder and head piece having a central apertureextending therethrough and a transverse slot forming lateral groovesextending from the opposite sides of the head piece to the centralaperture, electricity conducting cords passing through said lateralgrooves and central aperture, and a plug screwed into the outer end ofthe said central aperture and seating upon the said conducting cords, asset forth.

3. In cord grips for electric fittings and appliances, the combinationcomprising a holder, an insulating head piece integral with said holderand head piece having a central aperture extending therethrough and atransverse slot forming lateral grooves extending from the oppositesides of the head piece .to the central aperture, electricity conductingcords passing through said lateral grooves and central aperture, and aplug screwed into the outer end of the said central aperture and seatingupon the said conducting cords, as set forth.

In testimony whereof I have signed my 9 name to this specification.
